The Aston Martin Cygnet city car could be sold with the firm’s V12 engine if there is sufficient customer demand.

Sources suggest that a feasibility study has already been completed, and that the 6.0-litre V12 from its range-topping cars will fit the tiny city car’s engine bay without extensive modifications.

Other upgrades to allow the Toyota IQ-based Cygnet to handle the weight, horsepower and torque of the powertrain are said to be “significant but not insurmountable”. It is likely, however, that the V12 would have to be detuned significantly from the 510bhp it produces in the new DB9 and Vantage models.

The Cygnet is currently sold in one state of tune, powered by Toyota’s 97bhp 1.3-litre petrol unit.

If Aston gives the go-ahead for a production Cygnet V12 it is likely to be sold as a project car much like the Nissan Juke R has been. The Juke R, which fits the Nissan GT-R’s running gear into a Juke supermini body, sells for around £400,000. It was put into limited production, mainly for the Middle East market, following a positive reaction to the concept car’s creation.

This is obviously a joke. Are you seriously suggesting there would be a rear wheel drive front engine v12 in a Toyota iq? Firstly there is no room in the engine bay, secondly where's the transmission, prop shafts and rear differential going to fit?
